[JohnD.Heintz]

I couldn't post this to the Tracker at www.zope.org/Products/ZEO/Tracker=20
because the service was unabailable.

This is really high priority for us.  We installed Linux on two boxes bec=
ause=20
of a similiar problem on Windows and are getting panicy.

Thanks for any help,
John

We can't use ZEO (latest on StandaloneZODB) on Linux 2.4.x with mutliple=20
threads.

Getting the following traceback:

This code break when we start using multiple threads instead of just one.=
